Crump

“Don't you wish you may get it, Mrs. Crump? ” Grose says
Mrs. Crump, a farmer's wife, was invited to dine with Lady Coventry,
who was very deaf. Mrs. Crump wanted some beer, but, awed by the purple
and plush, said, in a half-whisper, “I wish I had some beer, now.” Mr.
Flunkey, conscious that his mistress could not hear, replied in the
same aside, “Don't you wish you may get it?” At this the
farmer's wife rose from table and helped herself. Lady Coventry, of
course, demanded the reason, and the anecdote soon became a standing
joke.
